In the world of canned fish, few confusions are as frequent as the one between sardines and sardinellas. Most consumers assume they are the same product in different sizes, and technically they are not wrong, but the real difference goes far beyond size. It affects flavor, texture, price, presentation, and, most importantly, the most appropriate use for each.
At Mercat del Ninot, we have been selling both for decades, and the most common question at the counter is always the same: "Which one should I get?" The answer depends on what you want them for, and this guide provides you with the criteria to make an informed decision.
What is a sardine and what is a sardinella
Sardines and sardinellas are the same fish: Sardina pilchardus, the European sardine from the Atlantic and Mediterranean. The difference is exclusively in age and size at the time of capture:
- Sardinella: young sardine, caught when measuring between 8 and 12 cm in length. It is between 1 and 2 years old. It is smaller, thinner, with finer bones and more tender flesh.
- Sardine: adult specimen, caught from 14-16 cm onwards. It is 2 or more years old. It is larger, meatier, with thicker bones and a higher fat content.
There is no rigid and official boundary between the two denominations. Canning regulations establish indicative ranges, but each producer applies their own selection criteria. What is consistent is that "sardinella" always implies a significantly smaller specimen than "sardine."
Comparison table: sardine vs sardinella
| Characteristic | Sardine | Sardinella |
|---|---|---|
| Size | 14-20 cm | 8-12 cm |
| Weight per piece | 20-40g | 5-15g |
| Pieces per can (standard) | 2-5 | 8-20 |
| Fat content | High (8-15%) | Medium (5-10%) |
| Bones | Perceptible, edible | Very fine, almost imperceptible |
| Texture | Firm, meaty, juicy | Tender, delicate, soft |
| Flavor | Intense, marine, deep | Mild, clean, elegant |
| Average price (can) | 2-6 € | 4-12 € |
| Best use | Cooking, hearty tapas | Appetizer, gourmet platter |
Flavor: the difference that truly matters
Size influences flavor because it affects two key variables: fat content and the flesh/bone ratio.
The adult sardine has more intramuscular fat, which translates into a more intense, marine flavor with more umami. When you open a can of large sardines in olive oil, the first bite fills your mouth with flavor. It is a product with character that makes no apologies. The bones are perceptible but perfectly edible (and an excellent source of calcium).
The sardinella, on the other hand, has a cleaner, more elegant, and more subtle flavor. The flesh is more tender, the bones are so fine they are imperceptible, and the overall experience is more refined. It's the difference between a strong aged cheese and a mild semi-cured cheese: both are good, but for different occasions and palates.
If you have never paid attention to this difference, we recommend trying both in parallel. Open a can of each, place them on a plate, and compare. The difference is immediately noticeable. Our guide to canned sardines delves into the quality criteria for choosing the best ones.

Price: why sardinellas are more expensive
Sardinellas are consistently more expensive than standard sardines, and there are objective reasons for this:
- Lower yield per piece: each sardinella weighs 5-15 grams compared to 20-40 grams for an adult sardine. To fill a can of the same drained weight, 3-4 times more pieces are needed.
- Higher handling cost: each piece is handled individually during canning. More pieces per can means more labor time per unit of product.
- More demanding selection: size uniformity is a visual requirement for quality sardinellas. Pieces that do not meet the size range are discarded or destined for lower-grade preserves.
- Limited season: the best quality sardinellas are caught at specific times of the year, when the young specimens have the optimal size and fat content.
- Gourmet positioning: the market associates sardinellas with a more premium product, allowing for a larger margin in the distribution chain.
This does not mean that standard sardines are a second-rate product. It means that the price of sardinellas reflects a higher real production cost and a different market positioning. Good Dardo sardines in olive oil at €3.25 are an exceptional product for their price.
Common presentations and formats
Canned Sardines
Adult sardines are usually presented in these formats:
- In olive oil: the classic and best-selling format. The oil preserves the moisture of the flesh and slightly softens the flavor. Dardo sardines in olive oil (12-18 pieces) are an example of quality standard sardines at an accessible price.
- In tomato sauce: tomato sauce provides sweetness and acidity that complement the intensity of the sardine. Our sardines in tomato sauce in a jar are perfect for those looking for a product ready to spread or add to pasta.
- Smoked: smoking adds a layer of complexity to the flavor that completely transforms the sardine. Smoked sardine fillets are an alternative to smoked salmon with more personality and at a better price.
- In escabeche (pickled): vinegar, paprika, and spices create a powerful and traditional flavor profile.
Canned Sardinellas
Sardinellas are generally presented in more refined formats:
- In extra virgin olive oil: the premium presentation. Uniform pieces, perfectly aligned in the can, covered with first-press oil.
- In spicy sauce or with chili: a touch of spice that complements the mildness of the sardinella.
- With lemon: lemon zest and aromatic herbs that highlight the delicacy of the fish.

When to use sardines and when to use sardinellas
Choose sardines when:
- You are going to cook with them (pasta, pie, hot salad).
- You are looking for a hearty and satisfying bite as a tapa or snack.
- Budget matters and you want maximum flavor per euro.
- Sardines are accompanied by other strong ingredients (tomato, peppers, garlic).
- You are preparing a dish where the sardine is flaked or mixed.
Choose sardinellas when:
- You are going to serve them as an appetizer or starter where the fish is the star.
- You are assembling a gourmet conserve platter to share.
- You are looking for a delicate product for special occasions.
- Bones are a problem (children, people with difficulty eating bones).
- You want to impress visually: open cans of sardinellas are much more attractive.
Either works for:
- Toasts and canapés (adjusting the quantity according to size).
- Cold salads with vegetables and vinaigrette.
- Eating directly from the can with good bread.
Smoked sardines: a third option
If you are interested in sardines but are looking for something different from the classic oil-packed conserve, smoked sardines deserve your attention. The smoking process radically transforms the flavor and texture of the sardine: the flesh acquires smoky notes, becomes firmer, and develops a complexity that places it in a completely different register.
Our smoked sardine fillets and the 120g smoked sardine loins are products that surprise those who try them for the first time. For hospitality or large families, the 900g format offers the best value for money.
How to preserve canned sardines and sardinellas
Both follow the same preservation rules:
- Unopened: in a cool, dry, and dark place. Ideal temperature: 15-20 °C. Quality preserves improve over time during the first 2-3 years (like wine), developing deeper flavors and a silkier texture as the oil penetrates the flesh.
- Once opened: transfer the contents to a glass container with a lid, ensuring the fish is covered with oil. In the refrigerator, maximum 3-5 days.
- The oil from the can: do not discard it. It is oil flavored with the taste of the fish and is perfect for dressing salads, spreading on bread, or adding to a sofrito.
Frequently asked questions
Are sardinellas healthier than sardines?
There is no significant nutritional difference. Both are rich in omega-3, protein, calcium, and B vitamins. Adult sardines have slightly more fat and omega-3 per gram. Sardinellas have finer bones that are easier to digest. Both are excellent food.
Why are sardinellas more expensive than sardines?
For three reasons: more pieces are needed to fill a can (lower yield), each piece is handled individually (more labor), and selection for uniform size discards part of the product. The production cost is higher, and gourmet positioning also plays a role.
Do canned sardines and sardinellas contain bones?
Yes, both retain bones. Sardinella bones are so fine that they are practically imperceptible. Adult sardine bones are thicker and noticeable, although they are edible and an excellent source of calcium. If bones bother you, choose sardinellas.
Which sardine is best for children?
Sardinellas. The bones are finer, the texture more tender, and the flavor milder. For children starting with canned fish, sardinellas in mild olive oil are ideal. Sardines in tomato sauce also work because the sweetness makes them more appealing.
Do canned sardines improve with time?
Yes. Quality sardines in extra virgin olive oil develop deeper flavors and a silkier texture during the first 2-3 years. The oil penetrates the flesh, and the flavors harmonize. This is called 'aging' preserves.
Can you make a conserve platter with only sardines?
Absolutely. A platter with sardines in olive oil, in escabeche, in tomato sauce, and premium sardinellas offers a great variety of flavors and textures. Add breadsticks, olives, pickles, and good olive oil for a complete appetizer.
